The regular price of a scooter is $70. It is on sale for $28 off. What PERCENT do you save? (Guess and Check is a good strategy for this problem)

Answer:

B. 2 years

Step-by-step explanation:

use y = mx + b

y = total number of sell outs = 168

m = sell outs per month = 7

x = months

b is not needed for this

168 = 7x

divide both sides by 7

x = 24

divide 24 by 12 to get the number of years

years = 2

Answer:

the answer to this question is B. 2 years

Answer:  Area 89m^2

Step-by-step explanation:

To find the area of the rectangle we multiply

Base * Height = Area

8 * 13 = 104

Now we find the area that isn't shaded

I inference that the base of the triangle is 5m  

5 * 6 = 30

Now divide that by 2

30/2 = 15

Subtract 15 from 104

104 - 15 = 89m^2

Answer:

1/0.4=10/4=5/2...............

Answer:

x = 53

Step-by-step explanation:

Similar means that the corresponding angles are congruent (the same) - basically what this means is that ∠L ≅ ∠G, ∠M ≅ ∠J, and ∠N ≅ ∠H.

Since we know that the angle measures in a triangle should add up to 180 and we know the measures of ∠L and ∠M already, we can do

180 =  67 + 60 + N

So, N = 180 - (67 + 60) = 180 - 127 = 53.

Since ∠N ≅ ∠H, ∠H = 53.

Answer:

172000

Step-by-step explanation:

Population growth from  2010 to 2015 if population increased by 8% =

1.08 x 168,000. = 181440

Population growth from  2015 to 2020 if population decreased by 5% =

0.95 x 181440 = 172,368

Rounding off to the nearest 100 people = 172,000

The population in the year 2020 is 172,368.

Since

In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 5%.

So,

[tex]= 168000 \times 1.08 \times 0.95[/tex]

= 172,368

hence, The population in the year 2020 is 172,368.

I had this question as well it's right for plato

Answer and explanation:

A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm

Answer:

I'm so sorry I only found the area of the first triangle with the measurements 11, 10 and 17

I'll show you how to find the area

Step-by-step explanation:

The formula for a triangle is base x height divided by 1/2

For the first triangle the base is 11 and the height is 10

base(11) x height(10) = 110 then divide 110 by 1/2 = 55

so the area of the first triangle is 55.

Sorry again this is only the area of the first triangle.

Answer:

A

Step-by-step explanation:

We have the equation:

[tex]x^2-2x-2=0[/tex]

We can use the quadratic formula. In this case, a = 1, b = -2, and c = -2. Hence:

[tex]\displaystyle x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-2)}}{2(1)}[/tex]

Evaluate:

[tex]\displaystyle x=\frac{2\pm\sqrt{12}}{2}[/tex]

Simplify:

[tex]\sqrt{12}=\sqrt{4}\cdot\sqrt{3}=2\sqrt{3}[/tex]

Hence:

[tex]\displaystyle x=\frac{2\pm2\sqrt{3}}{2}[/tex]

Divide:

[tex]x=1\pm\sqrt3[/tex]

The correct answer is A.

Answer:

The ordered pair (15, 12) means that 15 pounds of beans cost $12.

Step-by-step explanation:

(20, 16)

(x, y)

x is along the x-axis and y is along the y-axis.

x = 20 = 20 pounds of beans

y = 16 = 16 is the cost of the beans

(15, 12)

x = 15 is 15 pounds of beans

y = 12 is 12 for the cost of the beans

Answer: 15 pounds of beans costs 12 dollars

Step-by-step explanation:

if the x-axis represents the pounds of beans, then any x-coordinate will be beans.

Answer:

[tex]120x^4\sqrt{2}[/tex]

Step-by-step explanation:

First we need to break down the numbers in the radicals into its factors

so

12= 3*2*2

x³=x*x*x

Which means we have

[tex]10\sqrt{3*2*2*x*x*x}=20x\sqrt{3x}[/tex]

and

[tex]2\sqrt{2*3*x*x*x*x*x} =2x^{2} \sqrt{6x}[/tex]

Because the radicand (the small number that goes up top) are the same we can just mulitply the two from here

which means we have

[tex](20x*2x^2)\sqrt{3x*6x}=40x^3\sqrt{18x^2} \\\sqrt{18x^2}=\sqrt{2*3*3*x*x} =3x\sqrt{2} \\=120x^4\sqrt{2}[/tex]

Answer:

y = - 3

Step-by-step explanation:

Given the 2 equations

6x + 11y = - 3 → (1)

4x + y = = 17 → (2)

Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x

24x + 44y = - 12 → (3)

- 24x - 6y = - 102 → (4)

add (3) and (4) term by term to eliminate x

0 + 38y = - 114

38y = - 114 ( divide both sides by 38 )

y = - 3
